You use acrobatics to move quickly through your opponents, catching them off guard.

Acrobatic Prowess

When you choose this archetype at 3rd level, you gain proficiency in the Acrobatic skill if you don't already have it. Your proficiency bonus is doubled for any ability check you make that uses this skill.

Quarterstaff Training

Starting at 3rd level, you can treat a quarterstaff as a finesse weapon. If you are holding a quarterstaff while balancing on a narrow surface, you gain advantage on any Dexterity (Acrobatics) checks made to keep your balance.

Tumbler

Starting at 3rd level, you are difficult to pin down during a fight. You can move up to half your speed as a reaction when an enemy ends its turn within 5 feet of you. This movement doesn’t provoke opportunity attacks.

Boundless Mobility

At 9th level, your walking speed increases by 10 feet. If you have a climbing or swimming speed, this increase applies to that speed as well.

Spring to Action

Starting at 13th level, you excel at surprising your opponents and acting first in a fight. You have advantage on initiative rolls. In addition, the first creature you hit during the first round of a combat becomes easier for you and others to strike; attack rolls against that target have advantage until the start of your next turn.

Acrobatic Strike

Starting at 17th level, you can strike with deadly speed. If you take the Attack action on your turn, you can make one additional attack as a bonus action. This attack can benefit from your Sneak Attack even if you have already used it this turn, but you can't use your Sneak Attack against the same target more than once in a turn.
